Overview
Today’s feed splits between practical AI you can run on your desk, sweeping gains in AI video, and hard tech milestones in energy and neurotech. There is fresh movement on personal AI that works with your own data, a new open-source agent for computer use, and creator tools from Blender to Grok. Tesla pushes upstream with a lithium refinery, Neuralink shows progress in the UK, and culture chimes in with J. Cole’s next chapter. Even vector calculus gets a clear visual that ties back to modern AI.
The big picture
Stokes’ Theorem, animated and intuitive
Alec Helbling’s visual makes the circulation-equals-flux idea feel concrete, with arrows and shaded patches showing cancellations around a loop and its spanning surface. Replies even touch on the Kelvin-Stokes naming history, and Helbling links it to divergence, a reminder that this maths underpins fields from electromagnetism to diffusion models.
An open-source computer-use agent in two days
Or Hiltch unveils Openwork AI, an MIT-licensed agent for automating desktop tasks. It uses your own model keys, isolates browser sessions for tighter security, and leans on a speedy dev-browser setup. The demo pulls property data, drafts a Gmail update, and wraps in under two minutes, a clear shot at tools like Anthropic’s Cowork.
Quad Adder makes clean quads on curves in Blender
ModelingHappy spotlights a free addon by Kushiro that adds quads along edge borders on curved surfaces without warping. The clip shows a sphere, a deformed cube, and a character model, with rotation controls and face orientation to keep tidy topology.
Opt-in human data at scale
Avi Patel claims a record opt-in data push, with 200k contributors uploading 3 million files daily and 12k structured datasets across egocentric video and medical scans. The thread drew a nod from Astrid Wilde, and it lands squarely in the debate on how to feed robotics and multimodal models with real-world data, not just synthetic sets.
Neuralink’s first UK patient
Tesla Owners Silicon Valley shares footage of Paul, who has motor neurone disease, using a computer by thought hours after surgery at UCLH. It adds to the PRIME study’s thread of results beyond the US, with praise and ethical questions in the replies.
Tesla’s lithium refinery, two views
Tesla North America shows its Corpus Christi lithium refinery, built for battery-grade lithium hydroxide from spodumene with a simpler, lower-emission process that yields an analcime coproduct for concrete instead of hazardous waste. Sawyer Merritt’s post adds scale and speed, while noting local concern over heavy water use in drought-prone South Texas.
J. Cole teases Disc 2 - Track 2
A short, cinematic teaser points to The Fall Off as a double album with a film-like structure. Fans are reading the room, guessing at timing and narrative links across the two discs.
Cash App Pay Links
Cam Worboys announces Pay Links, so you can make a payment URL, share it on X, Snap, or text, and get paid. The demo is short and clear. Early asks in replies include bitcoin support and comparisons with Venmo and Zelle.
Grok Imagine, quick image edits
DogeDesigner walks through a simple flow to upload an image in the X app, add a prompt, and transform it. The example flips a fluffy dog photo into a retro control room scene, which sparked a flurry of user riffs.
Gemini’s Personal Intelligence beta
Google’s Josh Woodward introduces opt-in connections to Gmail, Photos, and more, so Gemini can answer in context, like suggesting tyres from your road trip history or pulling a number plate from a photo without training on your data. The pitch is personal help with clear controls and sources.
AI video: from solo creators to studio-grade shots
Min Choi compiles ten examples that mirror Hollywood tricks using Veo, Kling, and local models like LTX-2. Think motion-controlled character swaps, crisp 4K clips on personal rigs, and agents that stitch full anime PVs. The through line is that production value is getting cheaper and faster.
Indie dev truth: joy over jackpots
GitHub Projects shares a meme about quitting a $300k job to ship a todo app that made $20 in two years, with the punchline, “I was alive.” The replies pile in with similar stories and a repo link, a neat snapshot of why side projects stick.
Back to Cursor, and a playable AI arena
Dominik Scholz returns to the AI code editor to push ralv.ai, a StarCraft-like battler with agents as characters. The clip presents a forge-like hub for spinning up Claude, Gemini, and Cursor agents, and nods to praise for Cursor’s fast text input.
xAI is hiring
Elon Musk calls for engineers to build agents that match or surpass human computer use, with a link to Mohit Reddy’s note. It fits xAI’s long-stated aim to push core science through AI.
Antarctica, made with InVideo’s Agents & Models
InVideo shows a polished Antarctic short by 44creator, pairing Google’s Nano Banana Pro for photoreal base frames with Kuaishou’s Kling 2.6 for motion and native audio. Directors get prompt-level control for ice, snow, and pacing, without keyframes.
Higgsfield’s last-chance Kling offer
Higgsfield pushes a yearly plan that unlocks 30 days of unlimited runs across Kling 2.6, 2.5, O1 Video Edit, and Motion Control. Creators note the appeal during heavy production weeks, though some mention clip length limits.
Why it matters
- Personal agents are moving from chat boxes to real work on your machine, and into your own data with clear consent. Openwork, Gemini’s Personal Intelligence, and xAI’s hiring point to a near-term future where assistants navigate apps, files, and accounts with guardrails.
- Video creation is crossing a threshold. Tools like Kling and Veo let individuals hit studio-style results, while platforms package control over motion, look, and audio. Expect a boom in indie ads, music visuals, shorts, and game assets, and pressure on traditional budgets.
- The supply chain and health threads are concrete. A domestic lithium refinery strengthens battery output in North America, with environmental trade-offs to watch, and Neuralink’s UK progress inches assistive tech from lab demos to daily use.
- Creator tools keep lowering the bar to entry. A Blender addon that keeps quads in check, a quick image editor in X, and an AI-first code editor all shave time from idea to result.
- Data remains the scarce input. Large, opt-in human datasets could lift robotics and multimodal systems, but consent, privacy, and fairness will define which platforms earn trust.
- Culture adapts in real time. From J. Cole’s double-album tease to a meme about side projects, the creative economy keeps moving with these tools, not just talking about them.
